A W-band constructive wave oscillator in 130-nm SiGe BiCMOS

In this paper we present a deterministic W-band constructive-wave oscillator (CWO) designed and simulated in 130-nm SiGe BiCMOS. A six-section CWO produces 95 GHz multi-phase oscillation signals that are distributed along the ring with 60 degree phases. The CWO circuit occupies a total area of 0.59 mm × 0.53 mm and dissipates 67 mW from a 2V supply. The six-phase CWO operating at 95 GHz has -10 dBm output power into 50 ohm load with a phase noise of -81 dBc per Hz at 1 MHz offset.
